Plantscape leads the state with more nationally certified interior landscape managers and technicians on staff than any other company. To attain national certification through Naional Association of Landscape Professionals (NALP), plantscapers must achieve prescribed benchmarks, attend and complete a variety of rigorous study classes, and then pass detailed certification exams. The entire study and testing process takes about three years. We are proud of the hard work and dedication it takes to become nationally certified.
